[CentOS] How to check server kernel support 32 Gb RAM (X86, CENTOS 4.7)??
we have CENTOS 4.7 (X86) on DELL server, I already put 32 GB RAM on it. I can use "top" or "free" to check memory and it did show 32 GB. I check REDHAT site and found it say: The "SMP" kernel supports a maximum of 16GB of main memory. Systems with more than 16GB of main memory use the "Hugemem" kernel. I use "uname -r" to check kernel and it show: # uname -r 2.6.9-78.0.13.ELsmp It did NOT show "Hugemem", does this server kernel support 32 GB or not? If NOT how can I change kernel to "hugeme"? Thanks. ______________________________________________________________________________________________________ ?????????Yahoo!??????2.0????????????? http://tw.mg0.mail.yahoo.com/dc/landing

Your better off using 64-bit for this if you can, 32GB is quite a bit of ram to use PAE with. nate
